MINING UNIT FOR EXTRACTION OF MINERAL MATERIALS LAYING IN THE FORM OF LAYERS OR ARRAYS, AND MINING COMBINE

摘要

1. A mining machine for the extraction of mineral materials lying in the form of layers or an array, a conveyor device for transporting the extracted material, a bed installed with the ability to move along the conveyor device, at least one drum equipped with tools for material development, and installed with the possibility rotation around the axis of the drum and height adjustment relative to the frame of the harvester using a swivel arm, characterized in that the axis of the drum is essentially parallel to systematic way movement of mining combine, tools for extracting material mounted on the tool carrier groups, which are arranged on the circumference of the drum rotatably about a rotation axis arranged transversely with respect to the axis barabana.2. The miner according to claim 1, characterized in that the axis of the drum is substantially parallel to the direction of travel of the miner. The miner according to claim 1, characterized in that during mining during mining, the axis of the drum is inclined with respect to the direction of movement with an angular displacement between the axis of the drum and the direction of movement, preferably equal to or less than ± 6 °. 4. The miner according to claim 1, characterized in that the position of the axis of the drum relative to the direction of movement is adjustable by the angle (α) of inclination. The mining machine according to claim 1, characterized in that the axis of rotation of the tool supports are located at an angle (γ) of inclination with respect to the normal to the axis of the drum interacting with them, �
